Now I Found on internet some Dual fans' Setup, with Low profile...
I'll Search on Local Car Parts' Stores ASAP for something similar.

...My BumbleBeast tend to Start the electric fan when Temp reaches Above the Middle and I Don't Like That... I Like to keep the engine Cooler. Now with the Fixed fan it Usually Runs around 1/4 temp gauge.
So, I Must change the Thermo Switch... isn't it?
Are those Standard? ... So I could find a Lower temp thermo Switch and swap the actual one...

Today I Went to some Junk Yards (Locally known as Yonkers) and some car parts' stores, searchin' for a dual fan setup, like the one in the picture above.
My Subie's Radiator has the Followin' measurements:
(not Perfect measurements taken, just to have an idea of the size I'll need to search)
- Wide: (almost) 25 inches, not measuring both vertical Tanks, just the Cooling core.
- Tall: 14 inches, from Upper frame to Lower frame.
- Free Space from the Pulley to the Radiator: (Thickness available) 2½ inches. (Maybe a Li'l more)
interesting is that I Found in a Junk Yard, a Complete Radiator that has a Frame with Twin Fans, it belongs to a Toyota Corolla.
The Frame with Twin Fans has the following measurements:
- Wide: 24 inches, from side to side of its frame.
- Tall: 14 inches, from Upper frame to Lower frame.
I cannot measure its Thickness very well because it was still mounted on the Corolla Radiator, but seemed like one of those fans has 2 inches thickness while the another one 2½ inches, by coincidence, the Slim fan was at the Driver's Side where the slim one is needed, while the thickest fan was on the Passenger's side:
I'll Wire both at the Same imput.

Found 12 inches Brand New (chinese) Radiator Fans, some very Slim... 1½ inches!
The cost of two of those will Raise up to $ 75.ºº US Dollars, Plus I must build a Small frame to attach both to the Subies Radiator... Could end costing the Same than the Toyota's ones, but those last ones 'could' have better Quality.
What do you think about?

That means that the Stock A/C electric fan has a permanent Positive (+) and the Switching line is the Ground (-) isn't it?
So I can run a Relay with direct positive and ground to the New fan, and obtain the Switching signal for the relay, from the Stock A/C Fan's Ground; isn't it?
Could you post pictures of your Dual electric fan setup, please?
Also, about this:
I am a little bit confused... Why don't you leave the Waterpump's Pulley without screws?
those won't be needed anymore without the Clutch fan.

...The fan is wired to the relay, the relay is then fed to ground and battery positive, and the yellow wire coming off the relay is to go to the switch that turns on and off the stock fan. ...

I'll take some pictures tomorrow.
This is the 12 inches Brand New (chinese) Radiator Fan, very Slim... 1½ inches!

This is the Clearance
Between the Honduran Made two-row Radiator
and the Waterpump's Pulley:
Of course I Plan to Substitute the Stud Bolts with Normal Head Screws.

Here you can see the Old Fans' Setup...
...and here you can see How I did Fixed the Clutch Fan in year 1993:

Stubies setup appears to be identical to mine aside from where the fan came from...
... If the switch he is speaking of is the thermal sensor, ours are wired the same as well.

I Wonder if the Stock wiring could be enough to power this twin electric fans at the same time:
or maybe a pair of these:
or those will "swallow" too much Power from the wires?
Posted 25 November 2011 - 01:31 PM
...and you obtained your electric fan from?
A early 80's EA81 Subaru with A/C.
OK, so the original subaru wiring powers your Subie's electric fans. Both, isn't it?

The Original electric fan on my subie feels somehow like "Tired" ... it works but is kinda Slow.
Here you can see it, with the Fixed fan.

add the picture.

Not exactly. The new fan is on a relay, so the actual power source is the battery. The original fan's positive provides the switched power for the relay, and the ground goes the new fan's ground.
